综合智能告警机组误告诊断关键技术及其应用
Key Technologies and Their Applications of Power Units False Alarm Diagnosis in Integrated Smart Alarm
摘要
Abstract
The integrated smart alarm is one of the core functions of real-time monitoring and early warning applications in the smart grid dispatching and control system.Aimed at the false alarm caused by integrated smart alarm which cannot effectively distinguish the tripping and manual halt of power units,and based on an analysis of the application of the integrated smart alarm in north China grid and an on-site investigations into some plants,a real-time acquisition technology of manual halt signals of coal-fired and pump storage units is proposed innovatively and the optimized false alarm diagnosis logic of power units is presented based on steady and dynamic (PMU) data.The technology is implemented in the operating system of North China grid and effectively decreased the false alarms.The result proves the reliability of the technology in addressing the false alarm problems.关键词
